I'm having the same issue. I really don't want to have to redo the massive amount of time I put into it. For now, it just sits open on my computer and I'm keeping my fingers crossed

So for me personally the issue here was with the name of the image files. They had too many characters in them I believe, or too many numbers? Renaming the images did not fix the set file however. So basically what I did was rename my image files, then I created a new blank set. Then I copied my old broken set into the new set. I believe then I had to replace the images with the newly renamed versions.
